Assessment of Demographic, Clinical Indexes and Biomedical Risk Factors of Cardiovascular Disorders in Patients Undergoing Coronary Artery Bypass Graft Surgery in NAJA Vali-e-Asr(A) Hospital inTehran- Iran in 2008

Cardiovascular diseases (CVDs) and specially coronary artery diseases (CAD) are of the main causes of mortality and morbidity in the world. Preventing the risk factors of these disorders not only may reduce their incidence in the population، but also increases the efficacy and improves the prognosis of expensive therapies that are being used for cardiovascular patients. Most of the patients suffering from advanced coronary artery disease may need coronary artery bypass graft surgery (CABG). Therefore identification of risk factors of atherosclerosis and CAD is of the most valuable steps toward finding proper therapeutic options. This study was a cross-sectional descriptive retrospective study. Medical records of patients who underwent CABG were reviewed. Records gathered from Vil-e-Asr (A) hospital medical archive department. Demographic data، lab results، physical examinations and risk factors related to CAD have been extracted from the records. Total of 120 patients have been studied، 119 were male and 1 female. Ninety two (76. 7%) have had no history of cigarette smoking and 28 (23. 3%) were smoking. 27. 5% of patients have had past medical history of diabetes mellitus which 95% of them were taking oral agents. In biochemical assessments، 20% of patients have had high levels of fasting blood sugar and 33. 3% were having impaired fasting glucose. 18. 3% of patients have had history of dyslipidemia. 30. 8% of patients were overweight (BMI = 24. 7 – 26. 9) and 35% were in grade 1 obesity (BMI = 27-29. 9) and 15. 8% were suffering from morbid obesity (BMI>30). 38. 3% of patients have had history of high blood pressure. Results of this study shows that interaction and effect mechanism of risk factors of CVDs and effect of other factors like behavioral، genetic and biomedical on them makes a complex field of interactivity between factors that shows the necessity of more studies.
